Serial Communications Ports
- Connector X10: to connect an
RS232/485 terminal (also for setup
purposes). Through this port, using
the Modbus protocol (master/slave)
or serial ASCII the PLC can connect
a fieldbus network;
- The RS232 cable must be shorter
than 15 m;
- Connector X11: RS485 port to
connect a fieldbus network using
the Modbus protocol (master/
slave) or serial ASCII;
- These two ports can be configured
using the DIP switches on the
right of the X10 connector;
- Isolation from other electronics:
1600 V.
